" TENDEVR-ISCOOP.

SPECIFICATION forming part of Letters Patent no. 531,191, dated Decemberis, 1894.

Application filed September 15, 1894. Serial No. 523,070. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM F. KIESEL, Jr., a citizen of the UnitedStates, residing at Altoona, in the county of Blair, in the State ofPennsylvania, have invented a certain new and useful Improvement inTender-Scoops, of which the following is a true and exact description,reference being had to the accompanying drawings, which form a partthereof.

My invention relates to tender scoops, which are designed to raise waterfrom a trough, usually placed between the rails of a railroad track, andconvey it into a tank usually carried by thetender of the locomotive. Asheretofore constructed, a serious defect in these devices has been thatthe power necessary to lift the dipper from the trough increases withthe speed at which the tender is moving. x

The main object of my invention is, there fore, to so construct thescoop that the power, necessary to raise the dipper, will be independentof the speed,- and to effect this end my invention consists in sopivoting the dipper that it will be practically balanced and unaffectedby the pressure of the inflowing water.

My invention further consists in various details of construction, whichwill be more definitely pointed out hereinafter.

My invention will be best understood as explained in connection with theaccompanying drawings, in which-- Figure 1 is a side view of thepreferred form of my scoop, the tender on which it is supported beingshown in central vertical section. Fig. 2 is a front View of the scoopand looking from the right of Fig. 1. Figs. 3 and 4 are enlarged detailviews of the yoke on which certain stops are supported which serve tobear the strain due to the inflowing water when the scoop is inoperation. Fig. 5 is an enlarged sectional view of the dipper proper.Fig. 6 is a front view of the dipper.

Fig. .7 is a detailed view of the preferred form of frame to which .the'dipper ispi'vo'ted, and Fig. 8 is a side'view of this frame.

T is a tender, or other suitable vehicle, having a tank T. p

T is a tube or conduit opening into the tank T.

T is a suitable conduit or tube projecting below the tender which servestoreceive and convey to the tube T the water raised by the dipper.

A is the dipper, which is adapted to dip into a trough as N (see Fig. 2)and raise water therefrom as the tender moves. Heretofore, as has beenstated, the dipperA has been so pivoted that the eifect of the inflowingwater was to tend to hold the lip A of the dipper beneath the surface ofthe water, making it difficult to raise it, and this action of the waterincreased with the speed of travel of the tender. To overcome thisobjection,I form and pivot the dipper in a suitable supporting frame insuch a manner that the pressure of the ascending column of water actingat the rear of the pivotal point will tend to counterbalance thepressure of the water acting on the front of the dipper.

Preferably the dipper is so shaped and the pivotal point so chosen thatthe pressure at the rear of'the pivot will be'substantially equal tothat on the front of the dipper so that a balanced dipper will beprovided. In the particular construction shown,fth e dipper A is ofsubstantially uniform curvature and the pivot point a, is taken ataboutthe center of the dipper. The pivoted point may of course, ifdesired, be placed to the front of the center when the effect of theinflowing water will can be secured to the tender'in any way, or

the tube T or a continuation thereof, .may

constitute the frame to which the dipper ispivoted, but I prefer to forman intermediate joint piece, as indicated at O, to which is secured theframe B, to which is pivoted the dipper. The joint piece 0 makes a jointat c with the end 25 of the tube T and, as the joint piece 0 is pivotedto the tube T at c, the joint 0' is of a curvature, whose center is atc. The frame B is preferably formed integral with the joint piece 0,.andconsists, as shown, of two arms B B, which embrace the dipper A. Thedipper is pivoted to the frame B at a a, substantially as described.

Any suitable means, as the lever H, rod h, bell crank lever h, and links71, may be employed to raise and lower the dipper,'tl1e links 72 beingshown pivoted on stud h on the front of the dipper.

The dipper makes a joint at a. with the joint piece 0, the center ofcurvature of this joint being the point a. At a a are stops which areadapted to limit the swing of the dipper on its trunnions at a a. Thesestops can, of course, be arranged in any suitable way, but are veryconveniently arranged, as shown, on the dipper. I also prefer to providea suitable support, which will transfer to the main frame of the tender,all strains due to the intlowing water, and I also provide acounterbalance for the frame and dipper.

As shown, D is a yoke which is supported from the tender by a suitablerod or rods as d d.

E E are rods or links which are connected to the frame B at b, and whichhave stops, preferably adjustable, which, when the dipper and the frameB are in their lowermost position, as shown in Fig. 1, are adapted torest firmly on the yoke, and so support the dipper directly from thetender frame. Between the upper end of the stops and the yoke I insertsprings S S so as to counterbalance the weight of the dipper. In theparticular construction shown, the rods E have their upper ends threadedand sleeves e are screwed thereon. The springs S bear against the upperends of the sleeve, either directly, or through a washer, as indicatedat a", Fig. 3, and tend to hold the frame B and the dipper in a raisedposition. When the dipper is lowered, the ends 6' of the sleeves bearagainst platforms D on the yoke and so form a rigid support which takesup all the strain due to the water. By suitably adj usting the sleevese, the depth to which the dipper can project into the trough N can bevery conveniently regulated.

stiffening bars, as F, may be arranged, as

shown, to further support the end of the,

tube T In operation, the dipper on a rapidly moving tender is loweredinto the water which immediately rushes into it. When it is desired toraise the dipper, the lever H, or other raising n1eans,is suitablyoperated. The dipper first turns on its pivot points a till its lip A isout of the water, there being but little difficulty in lifting the lipout of the water, no matter how fast the train is traveling on accountof the balancing of the dipper. If it is desired to raise the dipperfarther than would be convenient to do by turning it on the trunnions ata a, the frame B is employed and when the stop a abuts against thisframe, both it, and the dipper carried thereby, turn on the pivots at cand are raised entirely clear of the road bed.

Having now described my invention, what teracting at the rearof thepivot will be sub-- stantially the same as the pressure on the front ofthe dipper, whereby the dipper will be practically balanced at allspeeds of the tender.

3. In a tender scoop, the combination with a suitable supporting frame,of a dipper of substantially uniform curvature, pivoted at substantiallyits central point on said frame so that the pressure of the ascendingcolumn of water acting at the rear of the pivot will tend tocounterbalance the pressure of water on the front of the dipper.

4. The combination in a tender scoop, of a suitable supporting frame, adipper pivoted to said frame as described and so that the pressure ofthe ascending column of water, acting at the rear of the pivot will tendto counterbalance the pressure of water on the front of the dipper,stops to limit the swing of the dipper, and a pipe to convey away thewater collected thereby.

5. In a tender scoop, a suitable tube or conduit T secured to thetender, a joint piece C pivoted to said tube T and a dipper pivoted tosaid joint piece 0 so that the joint piece and dipper can haveindependent movements.

6. In a tender scoop, a tube or conduit '1 secured to the tender, ajoint piece 0 pivoted on said tube T a frame secured to said joint piece0, and a dipper pivoted substantially as described, on said frame, sothat the pressure of the ascending column of water at the rear of thepivot will tend to counterbalance the pressure of water on the front ofthe 1 dipper.

, and means for raising and lowering the dipper so that on raising thedipper it will first swing on the frame till clear of the. water, andthen rise with the frame and joint piece.

8. In a tender scoop, the combination with a pivoted frame, of a dipperpivoted substantially as described on said frame as and for the purposespecified, and a counter balance for the frame and dipper.

9. In a tender scoop, a pivoted frame B, a dipper pivoted as describedon said frame s0 ITO as to render it substantially balanced at allspeeds, and a, suitable connection adapted when the frame B and dipperare in operation, and in their lowermost position, to support theframe'and dipper directly from the tender.

10.. In a tender scoop, a yoke D supported from the tender, at pivotedframe'B having a dipper A thereon and a rod or rods E connected to saidframe B and adapted, when said frame is in its lowermost position, to besupported 'on the yoke, whereby the strain due to the inrushing watermay be borne by the tender.

11 In a tender scoop, .a yoke D supported from the tender, a pivotedframe B havinga dipper A thereon and a rod or rods E c'onnected to saidframe B, stops on said rods, and a spring between the stop on each rodand the yoke, all substantially as and for the purpose specified. 3

12. In altender scoop, a yoke D supported from the tender, a pivotedframe B having a dipper A pivoted thereon, a rod or rods E connected tosaid frame B, adjustable stops on said rods, and springs for normallyholding the stops away from the yoke, all substantially as specified,and so that when the dipper is in its lowermost position and inoperation that the strain due to the inflowing Water may be borne by thetender.

13. In a tender scoop, the combination with a tube or conduit T? securedto the tender, of a joint piece 0 pivoted thereto, and making a joint 0'therewith, a frame B formed integral with the joint piece 0, a dipper Apivoted at substantially its middle point to the frame B, and making ajoint with the joint piece 0 at a, and means for raising and loweringthe dipper.
